Visual regression and website analysis

Pixel diffs with a threshold, element drift on the DOM, multi-device baselines, and a one-URL analysis with lab Core Web Vitals, images and security headers.

For: Front-end teams who ship visual changes on purpose and want to catch the ones they did not intend, and anyone who needs a fast, honest read of a page.

Capabilities

Pixel comparison with a threshold

A percentage, a pass or fail against the threshold you set, and a highlighted diff image.

Element drift on the DOM

Position, size and style changes of named elements between baseline and later version, on a second tab.

Multi-device capture

Baselines per viewport, so a mobile regression is caught on a mobile screenshot.

One-URL website analysis

Lab Core Web Vitals, network table, image audit, axe-core check, security-header grade and tech fingerprint from one real load.

Competitor comparison

The same analysis side by side for pages you name, including their Core Web Vitals.

Labels what it could not measure

Every analysis says what it did not reach rather than filling the gap.

How it works

Capture a baselinePer page and per viewport, from a URL or a recorded flow.
Compare a later versionSet the threshold; read the percentage and the diff image.
Accept or fixAn intended change becomes the new baseline; an unintended one is a finding.
Analyse any pagePaste one URL for the lab vitals, network, images, accessibility and headers.

What you receive, and what we do not do

Evidence ledger

Per comparison: Difference percentage, pass or fail against the threshold, and the diff image.
Per analysis: Lab LCP, INP and CLS, the request table, image findings, axe results, header grade, fingerprint, and what could not be measured.

Limits we state

Website analysis gives lab values from one load, not field data; Google grades on real visitors over 28 days.
It analyses exactly the page you give it; it does not crawl a site.

Plans: Visual regression is included from Solo Pro. See the metering table.

Questions buyers ask

Will every intended change show as a failure?

A change above the threshold is reported, intended or not; accepting it makes it the new baseline. That is the point: a visual change should be a decision, not a surprise.

Is the website analysis the same as a Lighthouse run?

It is a lab measurement from one real browser load, like Lighthouse, and it adds a network table, an image audit, an axe-core check and a security-header grade in one report. Neither is field data.
